Last yr, the vet I used told me a Health Cert was $15 and I could wait and get it when I needed it. When I called to get it 2 months later, he asked if it was for in-state or out-of-state. I live in PA and wanted one for a local fair and to go to OH. He told me since I was going out of state, that he had to check the horse. He came out and charged me a farm call for nothing, then he told me I needed 2 health certificates at $15 each. I've talked to other people in the area that use a different vet and they said when they call to get a HCert; the vet mails or they go to the office to pick it up. It costs $15, but they don't have to pay for another farm call. The vet I used last yr did tell me the in-state for the fairs would be good to the end of the yr, but out-of-state; you need one every 30 days.
